Basler ace 2 a2A4508-6gmBAS

a2A4508-6gm

The Basler a2A4508-6gmBAS is an ace 2 R series GigE Vision area scan camera built around the 1" Gpixel GMAX2518 global shutter CMOS sensor, delivering 4508 x 4096 px (18.4 MP) monochrome images at up to 6 fps. It uses a Gigabit Ethernet interface over an RJ45 connector with GigE Vision 2.0 and GenICam compliance, and offers 8/10/12-bit pixel depth with a typical 65.5 dB dynamic range. The camera has a C-mount, can be powered via PoE (IEEE 802.3af) or 12-24 VDC AUX power at about 3.7 W, and is rated IP30 for operation from -10 to 60 degrees C.

Technical overview

The Basler ace 2 a2A4508-6gmBAS is an ace 2 R series GigE Vision area scan camera built around the 1" Gpixel GMAX2518 CMOS sensor, a global shutter monochrome device that resolves 4508 x 4096 px (18.4 MP) at 2.5 x 2.5 um pixels. The global shutter is the headline characteristic for an installer: every pixel is exposed simultaneously, so parts moving on a conveyor or indexed on a rotary table image without the skew and smear a rolling shutter would introduce. Combined with the high 18.4 MP count, this camera is aimed at high-resolution inspection where you need both fine detail and geometric fidelity at the same time. The monochrome sensor means full per-pixel resolution with no Bayer interpolation, which is exactly what you want for edge-based metrology, defect contrast, and code or character reading where color carries no information.

The interface is standard Gigabit Ethernet (1000 Mbit/s) over an RJ45 connector, compliant with GigE Vision 2.0 and GenICam, which makes integration into existing PC-based vision stacks straightforward and supports cable runs up to about 100 m over copper without repeaters. The trade-off shows in throughput: at 18.4 MP the link supports roughly 6 fps (up to 6.3 fps optimized), so this is a precision-and-detail camera rather than a high-speed one. Pixel depth is selectable at 8, 10, or 12 bit against a typical 65.5 dB dynamic range, giving you headroom for surfaces with both bright specular highlights and dark features. Power is flexible for cabinet design: PoE per IEEE 802.3af delivers data and power on a single cable, or you can run 12-24 VDC AUX power.

Optically, the camera uses a C-mount, and the 1" sensor format (11.27 x 10.24 mm, 15.22 mm diagonal) sets the lens image-circle requirement. Because the pixels are small at 2.5 um and the sensor is large and high-count, lens selection is critical: you need a C-mount lens that both covers the 1" format and resolves to the pixel pitch, otherwise the system, not the sensor, becomes the limiting factor. The compact 29 x 29 x 55.5 mm body weighs 100 g, which eases mounting on gantries and tight fixtures. Environmental rating is IP30 over a -10 to 60 degC operating range, so the camera expects a relatively clean, enclosed environment or a protective housing rather than open washdown duty. Given the modest 6 fps and global shutter, this camera pairs naturally with strobed or pulsed illumination and hardware triggering to freeze motion and keep exposure short.

Best for

  • High-resolution surface and defect inspection on electronics, semiconductor, and printed parts where 18.4 MP detail is needed across a single large field of view
  • Dimensional measurement and metrology of moving or indexed parts, where the global shutter prevents geometric distortion
  • Industrial OCR/OCV and traceability code reading on mono surfaces where per-pixel monochrome resolution maximizes character and code contrast
  • PC-based GigE Vision systems that need a long (up to ~100 m) single-cable copper run with PoE for simplified wiring
  • Large-area inspection stations where one high-MP camera can replace several lower-resolution cameras to cover the same field

Selection notes

  • Throughput is the main constraint: at 18.4 MP the GigE link caps frame rate near 6 fps (6.3 fps optimized), so size your cycle time around this rather than expecting high-speed capture; if you need faster, reduce ROI or step up to a higher-bandwidth interface.
  • Lens is decisive at this resolution. You need a C-mount lens that covers the full 1" sensor format (15.22 mm diagonal) and resolves the 2.5 um pixel pitch, or the lens will limit effective resolution below the sensor's capability.
  • Plan lighting and triggering together: the global shutter is built to freeze motion, but you still want short exposures with strobed/pulsed illumination and a hardware trigger to make full use of it at 6 fps.
  • Mind the environment: IP30 and a -10 to 60 degC range suit clean, enclosed cells; for dust, mist, or washdown you will need an additional enclosure.
  • Decide your power path early. PoE (802.3af) gives single-cable power and data, but if your switch or budget does not support it, provision 12-24 VDC AUX power.
